Indoor to Outdoor. Need some advice

My friend just gave me a female plant He germinated the first day of January. Now the plant is almost 2ft tall and has started to flower. He has had it under a 400watt hps lamp since January and just started the 12/12 two weeks ago. The genetics are unknown but I assume its mostly indica because the its a short plant with wide fat leaves. The Plant is also very healthy.

I felt that it was very unsafe to keep the plant there because so many people knew about it. I moved the plant to my backyard(VERY SAFE). I live in Sothern California and the weather is great especially spring/summer. Will my plant survive outdoors or should I just buy a light and put it inside?
